Metal-free perovskite film and metal-free perovskite piezoelectric nanogenerators comprising the same

Abstract

The present invention discloses a metal-free perovskite film and metal-free perovskite piezoelectric nanogenerators comprising the film. The metal-free perovskite film is organic, lead-free and metal-free. The open-circuit voltage of the metal-free perovskite piezoelectric nanogenerators can reach 9~16 V and the short-circuit current of the metal-free perovskite piezoelectric nanogenerators can reach 38~55 nA. Also, the metal-free perovskite piezoelectric nanogenerators can be used as self-powered strain sensor of human-machine interface application and be adopted in in vitro electrical stimulation devices.
